Front

How do you find the slope from a table of values?

Back

To find the slope from a table, use the formula m = (y2 - y1) / (x2 - x1) using two points (x1, y1) and (x2, y2) from the table.

If a table shows the points (1, 3) and (4, 9), what is the slope?

Back

The slope m = (9 - 3) / (4 - 1) = 6 / 3 = 2.

How can you determine the equation of a line from a table?

Back

Identify the slope using two points from the table, then use the slope and one point to find the y-intercept and write the equation in slope-intercept form.
